To get going with debugging, you should only have to create an "HTML Application with TypeScript" after installing 0.8.1. In Debug mode, this will pass the --sourcemap flag to the compiler and will allow you to debug the TypeScript
directly after you hit F5 (and open in IE).

If you're trying it with your own project, you need to make the following changes:

Enable source map output in the compiler using the --sourcemap flag. You can tell if you have done this successfully by looking at the .js file that is output. If it has a "//@ sourceMappingURL=<filename>.js.map" style line at
the bottom, it's set correctly.

Include the .ts and .js files that you're using to debug in your project

My workflow w/ debugging w/ source maps is pretty bad right now have to restart a debugging session every time I want to refresh a page.

I'm probably just going to disable source maps for now. Typescript is sooo close to making me more productive, but this one is really taking away!

Thanks much,

Jon

EDIT: I disabled source maps and now have the benefits of the DEV time productivity in .ts and can debug in VS's great js debugger. I feel
very strongly that we should always be able to drop down into the .js and debug readable code even when source maps mature. I know there are other topics on this...floating around. Put me in the camp of idiomatic .js compilation so we
always retain the ability to debug readable .js! I respect others opinions on this, but there's no reason that we can't have both powerful .ts AND readable .js output.
